Problem 1:
Recently I have downloaded the new version of Parallel Desktop 3.0 Build 5584 as an update that was available. The pre-update version I had was already registered/activated and working Windows XP perfectly. Now however it is asking me for an activation key, which I dont have.

I am currently using a 15-day free-trial period to acces my user in the emulated Windows XP, but once that is ove O know not what I could save call someone from tech support. So, before I do that I want to know what my options are. Apparently, there is no activation code as the Parallel Desktop came free with the Mac.

tl;dr: I downloaded Build 5584 and my updated Paralel Desktop is now un-registered. What are my options?

Problem 2:
So I read that with 3.0 I can now run Age of Empires 3 (for windows) and other such games on Parallel Desktop. Can someone tell this poor n00b how exactly I can do this?
It was already installed prior to the update but whenever I tried to run it it said that my video card has 0MN and that a 64MB video card was required.
Im sure Im missing something incredibly obvious, and that there is a very easy way to play a game like AoEIII on an emulated Windows XP on a Mac but I lack the google-fu necesary to find it. So I ask you, can you help me on this matter?

tl;dr: How do I play window games on mac? I dunno lol.

Many thanks in advance and my deepest apologies if these are questions that have been discussed/asked to death.
